Add code to reflect USB ACM parity setting to the passthrough port alongside existing support for ACM baud rate changes. Some use cases for serial passthrough require specific parity settings.
For example, even parity is used and required by the USART protocol used in the STM32 system bootloader. This enhancement allows the use of standard flash programming tools such as STM32CubeProgrammer to flash connected STM based peripherals such as Receivers and Telemetry radios via serial passthrough. Some examples of such peripherals include the FrSky R9 receivers as well as various other STM based LoRa modules used by the mLRS project.
SERIAL_ORDER has been around for a few years now and UART_ORDER is
rejected by the hwdef script, so support for UART_ORDER and associated
processing in the hwdef script is removed, along with the order
conversion script.
Added support for stm32l4+ processor
- Added scripts for hwdef generation
- Tested in custom hardware prototype (stm32l4r5vit6)
- Tested all peripherals and auto pilot modes.

this fixes an issue reported on MatekH743, but also applies to other
boards. When not using DMA if there have been bytes written before the
auto flow control detection was enabled then these must be cleared
from _total_written so the flow control detection can work correctly
this changes the heuristics for UART TX DMA allocation to greatly
reduce the chances of DMA contention causing long delays on other
devices
This fixes issues with FETTec driver output and gimbal status messages
as reported by Amilcar and OlliW. The problem is particularly bad when
no GPS is connected to GPS1 on fmuv3 and derived boards (such as
CubeBlack)
key changes:
- remember the contention_counter across begin() calls, as the GPS
calls begin with new baudrates regularly
- added a is_shared() API to Shared_DMA, allowing the UART driver to
avoid TX DMA on shared streams when at low baudrates.
this fixes a problem with the automatic DMA disable on DMA contention
in UARTs. This fixes issue #14581
the problem was that while tx_dma_enabled was correctly set to false,
it would keep looping inside write_pending_bytes_DMA() if the data
arrived in the write buffer at a faster rate than it could be sent
out, which did happen with a mavlink stream rate of 4Hz. This means it
kept using DMA even with tx_dma_enabled set to false. The result was
that the automatic flow control code never got a chance to run and we
didn't switch back to non-DMA for these low baudrate contended UARTs
this gains about 20k of RAM, and has almost no impact on log download
speed at 921600 on a F427. The improved threading means we can afford
to have smaller buffers
refactor rcout into separate thread and process all dshot requests there
move uart DMA completion to event model
process dshot locks in strick reverse order when unlocking
convert Shared_DMA to use mutexes
move UART transmit to a thread-per-uart
do blocking UART DMA transactions
do blocking dshot DMA transactions
trim stack sizes
cancel dma transactions on dshot when timeout occurs
support contention stats on blocking locking
move thread supression into chibios_hwdef.py
invalidate DMA bounce buffer correctly
separate UART initialisation into two halves
cleanup UART transaction timeouts
add @SYS/uarts.txt
move half-duplex handling to TX thread
correct thread statistics after use of ExpandingString
set unbuffered TX thread priority owner + 1
correctly unlock serial_led_send()
don't share IMU RX on KakuteF7Mini
observe dshot pulse time more accurately.
set TRBUFF bit for UART DMA transfers
deal with UART DMA timeouts correctly
don't deadlock on reverse ordered DMA locks
change PORT_INT_REQUIRED_STACK to 128
When hw flow control is enabled check the CTS pin before we grab the
DMA channel to prevent a long timeout trying to send to a blocked port
from holding a DMA channel against another device
this fixes issue #16587
